Closes#57. Adds three OnInputAction switch cases (SelectLeft,
SelectDblLeft, UseSelected) and three private helpers
(PickAndStoreSelection, UseCurrentSelection, SendUse). Single-click
selects but does not Use; double-click selects + Uses; R hotkey
sends Use on the existing _selectedGuid. ImGui mouse-capture
filtering already happens in InputDispatcher — no new guard needed.
Diagnostic lines emitted for log grep:
[B.4b] pick guid=0x{guid:X8} name={label}
[B.4b] use guid=0x{guid:X8} seq={seq}
Also adds a one-line doc comment on _selectedGuid clarifying its
dual-purpose role (combat Q-cycle + interaction click), per the Task 3
review.
Build green; tests 1046/1054 (8 pre-existing-baseline fails
unchanged). Switch-case behavior verified at runtime via the Holtburg
inn doorway visual test (per spec §Testing → Runtime verification).

Retail's selection model is a single "current target" used by combat,
interaction, NPC dialog, and HUD alike - not two parallel selections.
Renames the existing combat-only field on GameWindow so the upcoming
B.4b click handler and the existing Q-cycle SelectClosestCombatTarget
share the same selection state.
Mechanical rename, no behavior change. Build + tests green.

Code review flagged two latent correctness bugs in Pick:
1. The single t = -b - sqrt(d) intersection skipped entities whose
5m bounding sphere contained the ray origin. Realistic at
point-blank range — if the player stands within ~5m of a door,
the near-plane sits inside the door's bounding sphere and the
door becomes unpickable. Standard fix: when t_near < 0 fall
through to t_far = -b + sqrt(d) (the sphere exit point).
2. The discriminant formula assumes |direction| = 1. BuildRay
currently normalizes so the assumption holds at the wire, but
the contract wasn't documented. Added an explicit
<param name="direction"> note.
New test Pick_RayOriginInsideEntitySphere_StillReturnsServerGuid
covers the inside-sphere case. Suite: 9/9 WorldPicker tests pass.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds Pick(origin, direction, candidates, skipServerGuid, maxDistance)
to AcDream.Core.Selection.WorldPicker. Iterates candidates, skips
entities with ServerGuid==0 (atlas/dat-hydrated statics — no server
identity) and the caller's skipServerGuid (the player self).
Geometric ray-sphere intersection at 5m radius (matches
WorldEntity.DefaultAabbRadius). Returns the nearest hit's ServerGuid
within maxDistance (50m default), or null on miss.
6 xUnit tests added: hit, miss, two-in-line-returns-closer, skip-guid,
skip-zero-server-guid, beyond-max-distance.

New AcDream.Core.Selection.WorldPicker static helper. BuildRay
unprojects pixel (mouseX, mouseY) through a view+projection matrix
pair into a world-space (origin, direction) ray. Used by
GameWindow.OnInputAction to drive entity picking on click.
Pure math, no state, no DI. Composes view*projection (System.Numerics
row-vector convention, matching the rest of acdream's camera path —
see GameWindow.cs:6445 FrustumPlanes.FromViewProjection). 2 xUnit
tests cover center-of-viewport (forward ray) and right-of-center
(positive-X deflection).

Original spec placed WorldPicker in src/AcDream.App/Rendering/ and the
test in tests/AcDream.App.Tests/, but AcDream.App.Tests doesn't exist
as a project. Moved to AcDream.Core.Selection where it conceptually
belongs (no App-layer deps; only WorldEntity + System.Numerics) and
where the existing AcDream.Core.Tests project can hold the tests.

Phase B.4b closes the M1-blocker discovered during the L.2g slice 1
visual test: the input dispatcher fires SelectDblLeft on click but
GameWindow.OnInputAction has no case for any Select* / UseSelected
action, so clicks silently die.
Spec creates the minimum new structure to close the gap:
- New static helper WorldPicker (BuildRay + Pick over WorldEntities)
- Rename _selectedTargetGuid -> _selectedGuid on GameWindow (unifies
combat + interaction selection per retail's single-target model)
- Three switch cases (SelectLeft, SelectDblLeft, UseSelected)
Two further L.2g handoff inaccuracies surfaced during exploration:
WorldPicker and SelectionState do NOT exist in src/ (handoff and
ISSUES #57 both claimed they did). BuildPickUp also doesn't exist;
only BuildUse / BuildUseWithTarget / BuildTeleToLifestone are present.
Spec accounts for the actual state and defers BuildPickUp + SelectionState
class extraction.
Visual verification scenario reuses the L.2g slice 1 reproducibility
recipe: one Holtburg inn doorway log captures both L.2g + B.4b.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
L.2g slice 1 is CODE-COMPLETE: parser + registry mutator + WorldSession
dispatcher + GameWindow subscriber (4 commits: 2459f28, d538915,
536a608, 108e386). Build clean, 6 new tests pass, baseline-stable
across the full suite. Per-commit + final integration code reviews
all approved.
Visual verification deferred: while running the Holtburg-doorway test,
Phase B.4's outbound Use handler turned out to be unwired. The wire
builders (InteractRequests.BuildUse), classes (SelectionState,
WorldPicker), input-action enums, and keybindings all exist — but
GameWindow.OnInputAction has no case for SelectDblLeft, so the click
silently does nothing. The inbound L.2g chain we just landed can't
fire until something sends an outbound Use.
This commit captures the handoff + reframes next-session work:
* docs/research/2026-05-12-l2g-slice1-shipped-handoff.md (NEW)
Full evidence: 4 shipped commits, end-to-end code flow, B.4
discovery explanation, 4 minor + 1 Important review notes
(the Important one is a test-coverage gap that the B.4b visual
test will settle automatically), reproducibility recipe,
next-session pick.
* CLAUDE.md
"Currently in Phase L.2" paragraph: L.2g slice 1 code shipped;
visual test deferred to B.4b. Next-phase-candidates list:
L.2g slice 1 (now done) replaced with the B.4b candidate
pointing at the slice scope.
* docs/plans/2026-04-29-movement-collision-conformance.md
L.2g section gains a "Current shipped slice (2026-05-12):" table
listing the 4 commits.
* docs/plans/2026-05-12-milestones.md
M1 phase-list updated: L.2g slice 1 (code) shipped; B.4 renamed
"B.4 / B.4b" with the gap-discovery note + B.4b shape.
* docs/ISSUES.md
New issue #57 (HIGH) for the B.4 interaction-handler gap.
Promoted to Phase B.4b; will close as
DONE (promoted to Phase B.4b) when B.4b's design spec lands.
* Memory file project_interaction_pipeline.md (in personal
memory dir, not in this commit) updated to reflect reality.
Next session: Phase B.4b (~30-50 LOC, 1-2 subagent dispatches,
~30 min). Subscribe SelectDblLeft -> WorldPicker.Pick ->
InteractRequests.BuildUse -> _liveSession.SendGameMessage. Same
Holtburg-doorway visual test verifies both L.2g slice 1 and B.4b
in one pass.

Two changes folded into one commit:
1. GameWindow subscribes to WorldSession.StateUpdated and routes the
parsed (guid, newState) pair into
ShadowObjectRegistry.UpdatePhysicsState. End-to-end wiring complete:
server SetState (0xF74B) -> WorldSession dispatcher -> StateUpdated
event -> GameWindow handler -> registry mutation -> next resolver
tick sees the new ETHEREAL bit and CollisionExemption short-circuits
the door cylinder. After this commit the M1 'open the inn door'
scenario is unblocked at the code-path level; visual verification
follows in Task 7 (user-driven).
The handler also emits a [setstate] diagnostic line when
ACDREAM_PROBE_BUILDING is enabled, giving a greppable trail when
the visual test runs.
2. Slice 0.5 freebie folded in: the [entity-source] probe lines now
include state=0x... flags=... so ETHEREAL flips are greppable
end-to-end from spawn through state change. Resolves the 'slice
1.6' suggestion from the L.2d ship handoff
(docs/research/2026-05-13-l2d-slice1-shipped-handoff.md).

Three changes folded into one commit:
1. New public StateUpdated event on WorldSession + dispatcher branch
for op == SetState.Opcode. Mirrors the VectorUpdated /
MotionUpdated event pattern. GameWindow will subscribe in the next
commit and feed the parsed (guid, newState) pair to
ShadowObjectRegistry.UpdatePhysicsState.
2. One-shot probe-gated hex-dump (ACDREAM_PROBE_BUILDING) emits the
first inbound SetState message's body bytes. Originally planned
as a separate slice 1.5 confidence-check on holtburger's claimed
12-byte payload vs ACE's GameMessageSetState.cs. Folded into the
dispatcher to avoid re-touching the same branch. The new
_setStateHexDumped guard keeps the log clean — auto-close every
30s would otherwise produce noise.
3. Doc-comment polish on SetState.cs requested by Task 1's code
review: remove false uncertainty about ACE's sequence-field width
(ACE's UShortSequence.CurrentBytes provably writes 2 bytes via
BitConverter), and align the 'total body size' phrasing with
VectorUpdate.cs's convention. Folded here to avoid churning the
file twice this slice.

New mutator that overwrites cached PhysicsState bits on every shadow copy
of the named entity. The existing CollisionExemption.ShouldSkip(...) check
(acclient_2013_pseudo_c.txt:276782) reads the same cached field, so a
post-spawn ETHEREAL flip is now honored on the next resolver tick without
any resolver-path change.
Retail anchor: CPhysicsObj::set_state at acclient_2013_pseudo_c.txt:283044.
Slice 1 scopes to the bare state-write — retail's cosmetic side-effect
handlers (0x800 lighting, 0x20 nodraw, 0x4000 hidden) don't fire for the
ETHEREAL bit and stay deferred.
Three TDD tests cover: ETHEREAL flip from 0->0x4; unregistered-entity
no-op; entity spanning multiple cells gets all copies updated.

DTO + TryParse for the GameMessageSetState wire message. The server
broadcasts this when an already-spawned entity's PhysicsState changes
post-CreateObject — chiefly when a door's Ethereal bit toggles on Use.
Wire format per holtburger SetStateData (validated against retail-format
servers): u32 opcode + u32 guid + u32 state + u16 instanceSequence + u16
stateSequence = 16 bytes total. Mirrors the existing VectorUpdate.cs
template.

L.2d slice 1.5 ship identified the Holtburg doorway blocker as a closed
Door entity (Setup 0x020019FF) whose PhysicsState.Ethereal bit flips
when the player Uses the door. The L.2d shape-fidelity work doesn't
cover this — the door's collision shape is correct; what's missing is
honoring the *runtime* state change.
L.2g is the new sub-phase that handles it. Scope is narrow:
* Parse inbound GameMessageSetState (0xF74B).
* Plumb the new PhysicsState value into ShadowObjectRegistry's
cached per-entity state so the existing CollisionExemption.IsExempt
already-in-place short-circuit sees up-to-date bits.
* Verify the Holtburg inn-door scenario: walk in blocked, Use door,
walk through, auto-close blocks again after 30s.
* Confirm UpdateMotion (NonCombat, On/Off) drives non-creature
entities (door swing animation).
Why a new L.2 sub-letter (and not B.4 or Door-special-case): the wire
mechanism (SetState flipping Ethereal) is also how ACE handles activated
traps, opened chests, spell projectiles becoming ethereal. Generic
infrastructure with doors as the verification scenario; lane is the
informal sixth "dynamic state."
Roadmap state:
* L.2 plan-of-record adds the L.2g section after L.2f.
* Milestones doc M1 phase list extended `a-f` -> `a-g`.
* CLAUDE.md status pointer + "next phase candidates" list updated to
name L.2g slice 1 implementation as the natural next step.
Risk: low. Wire-byte width has a hex-dump fallback path in slice 1
(holtburger says 12 bytes, ACE writes 16, capture settles it). ETHEREAL
plumbing already exists; we feed it new data. No resolver changes.

Adds two strategic-level documentation pieces:
- docs/plans/2026-05-12-milestones.md: morale + scope-management layer
above the phase-level roadmap. Seven milestones (M0–M7) from
"Connect & explore" to "v1.0", each defined by a concrete playable
scenario + freeze list + ~6–10 weeks of effort. M0 declared
retroactively done — ~25 phases shipped through 2026-05-12 are
frozen until M7's polish pass. Currently working toward M1
("Walkable + clickable world": L.2 collision + B.4 interaction).
- CLAUDE.md: new "Milestone discipline" section above "Roadmap
discipline" with the four motivation rules (one active milestone at
a time, frozen phases off-limits, recorded demo video per landing,
state both altitudes at session start). Plus "Work-order autonomy —
the meta-rule" paragraph delegating all work-order picks to Claude,
with a reinforcing bullet in "Things you should just do without
asking" under How to operate.
Triggered by the 2026-05-12 session where the user reported feeling
lost / jumping between things. Diagnosis: vertical-slice phase ships
never aggregated into milestone-level "done" events; decision fatigue
from constant work-order picks. Cure: milestone artifacts + scope
freezes + Claude drives the order, user reviews.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
User request: stop being asked "which should we work on next?" Claude
should drive the work-order autonomously per the milestone discipline +
roadmap, never present a menu of options, never pause for confirmation
between phases.
Two additive edits:
1. New "Work-order autonomy — the meta-rule" paragraph in the Milestone
discipline section, placed above the four motivation rules. Names
it the meta-rule that makes the others actually work. The user
retains the right to redirect; default is "Claude drives, user
reviews." If two next steps are genuinely equivalent, state the
choice in one sentence and start — don't ask.
2. Strengthened the "Continue to the next planned sub-step" bullet in
"Things you should just do without asking" under How to operate.
Adds explicit "You pick what comes next per the Milestone discipline
section — never present the user a menu like 'should we do X or Y?'
or ask 'what next?'. Just choose and announce the choice in one
sentence."
Saved as durable feedback memory in feedback_work_order_autonomy.md
(outside repo, in Claude's auto-memory).
Triggered by the 2026-05-12 session where the user reported feeling
lost / jumping between things; the diagnosis was decision fatigue from
constant work-order picks. Milestones doc (ecb0f2d) gave the structure;
this commit makes Claude responsible for executing it.

Introduce a morale + scope-management layer above the roadmap. Seven
milestones (M0-M7) from "Connect & explore" to "v1.0", each defined by a
concrete playable scenario and ~6-10 weeks of work. Each milestone hit
triggers a recorded demo video + a freeze list of phases that go
off-limits until M7's polish pass.
M0 ("Connect & explore") is declared done retroactively — ~25 shipped
phases through 2026-05-12 (terrain, network, audio, particles, chat,
input, streaming, WB rendering migration, sky/lighting, particle system,
combat/spell/item data layers) are frozen. Currently working toward M1
("Walkable + clickable world"): L.2 collision + B.4 interaction, ~4-6
weeks.
CLAUDE.md gains a "Milestone discipline" section above the existing
"Roadmap discipline" — sets the two-altitude orientation (milestones
above, phases below), names M1 as the current target, and codifies the
four motivation rules: (1) one active milestone at a time, (2) frozen
phases off-limits, (3) recorded demo video per landing, (4) state both
altitudes at session start.
Addresses the "everything is half-built" feeling caused by per-phase
vertical-slice ships never adding up to a milestone-level "done" event.

L.2d as scoped is essentially closed at the Holtburg site. The slice-1.5
trace settled the question: the "I can't walk through doorways" symptom
is a closed Door entity (Setup 0x020019FF named "Door") at the building
threshold, not a building-BSP-collision issue. Building BSP is healthy.
The two prior framings turned out wrong:
- L.2a handoff (2026-05-12): "per-cell walkability missing" — based on
hit attribution pointing at the building, missed the Door cylinder
also colliding per tick.
- L.2d slice 1 spec (2026-05-13 morning): "BSP shape fidelity, three
hypotheses X/Y/Z" — ruled out by the trace once the probe labeling
bug was fixed in slice 1.5.
Handoff doc captures full evidence, side findings (building double-
registration latent bug, missing PhysicsState in entity-source log),
and a candidates list for the next-session ordering discussion.
Plan-of-record L.2d sub-direction paragraph updated to match: "watch-
and-wait" mode, no more slices until a new shape-fidelity bug is
observed at a different site. Door-state handling becomes its own
sub-phase, scope deferred to project-ordering discussion.

First Holtburg-doorway capture showed all 191 [resolve-bldg] entries
labeled "n/a (cylinder)" — including hits attributed to the building
0xA9B47900 which [entity-source] confirmed was registered as type=BSP.
The label was a probe bug, not a real cylinder route.
Root cause: BSPQuery's grounded-path (Path 5) returns early via
`StepSphereUp(transition, worldNormal, engine)` when no step is already
in progress. The slice-1 side-channel write at line 1546 came AFTER
that early return, so it never fired for the dominant grounded-player
case. Compounding: StepSphereUp recurses into ResolveWithTransition →
FindObjCollisions, whose per-entity `LastBspHitPoly = null` clear
wiped any earlier write before the outer attribution emitter read it.
Fix:
1. BSPQuery Path 5: move LastBspHitPoly write to the top of
`if (hit0 || hitPoly0 != null)` blocks (both foot- and head-sphere),
BEFORE the StepSphereUp early return. Recursion-safe — the inner
resolve's BSP writes will overwrite with the inner entity's poly,
but for the dominant case (same wall hit on both outer and inner)
that's still the correct attribution.
2. TransitionTypes.FindObjCollisions: drop the per-entity clear of
LastBspHitPoly. With BSPQuery now writing at hit-detection time
instead of response-computation time, the side-channel value is
reliable without per-iteration zeroing.
3. TransitionTypes [resolve-bldg] emission: key the "n/a (cylinder)"
label on `obj.CollisionType` directly, not on LastBspHitPoly being
null. A BSP entity with a null poly now logs "n/a (BSP path —
side-channel not written, missing BSPQuery wire site)" so any
future BSPQuery path that's missing the wire is visible in the
trace rather than being silently mis-labeled.
Verified: build green, the 2 slice-1 tests still pass, 8 pre-existing
failures unchanged.
Spec: docs/superpowers/specs/2026-05-13-l2d-cbuildingobj-collision-design.md
First capture (showing the label bug): launch-l2d-slice1.log lines
12086-12120 (representative [resolve-bldg] entries for obj=0xA9B47900).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds ACDREAM_PROBE_BUILDING — a read-only per-shadow-entry probe that
captures full BSP collision evidence whenever TransitionTypes.FindObjCollisions
attributes a hit (via the existing L.2a slice 3 chain). One multi-line
[resolve-bldg] entry per attributed hit: partIdx, hasPhys, bspR vs
vAabbR, world-space entOrigin_lb, and the actual hit polygon's vertices
in both object-local and world space.
Paired with a one-time [entity-source] line at every ShadowObjects.Register
call site in GameWindow so entityId from a probe line is greppable to its
WorldEntity source within a single log file.
Plumbing: BSPQuery writes the resolved hit polygon to a new
PhysicsDiagnostics.LastBspHitPoly side-channel at the 5 SetCollisionNormal
sites in Paths 5/6 + CollideWithPt. TransitionTypes clears that field
before each shadow-entry dispatch and reads it back at the L.2a slice 3
attribution site to emit the probe line.
Spec component 4 originally described an out ResolvedPolygon? parameter
on BSPQuery.FindCollisions; the static side-channel achieves the same
observable behavior without plumbing through BSPQuery's recursive private
methods. Deviation noted in PhysicsDiagnostics.LastBspHitPoly's XML doc.
Reframes the plan-of-record's L.2d sub-direction paragraph: the 2026-05-12
handoff proposed porting CBuildingObj + per-cell walkability, but ACE
BuildingObj.cs:39-52 + named-retail acclient_2013_pseudo_c.txt:701260
show find_building_collisions is one BSP test on Parts[0]. Per-cell
walkability belongs to L.2e, not L.2d. L.2d slice 1 is the diagnostic;
slice 2 is the actual fix scoped from slice 1's evidence (one of three
hypotheses: wrong BSP loaded / over-registered parts / BSPQuery flaw).
Tests: 2 synthetic unit tests in PhysicsDiagnosticsTests.cs pin the
static API contract that the BSPQuery → side-channel → TransitionTypes
emission chain depends on. The multi-line line format itself is verified
by acceptance criterion 2 (live Holtburg-doorway capture) — covering it
here would require a heavy PhysicsEngine + Transition fixture for a
diagnostic-only emission.
Verified: dotnet build green; the 2 new tests pass; the 8 pre-existing
test failures listed in the L.2a handoff (MotionInterpreter GetMaxSpeed_*,
PositionManager.ComputeOffset_BothActive_Combined,
PlayerMovementController.Update_ForwardInput_*, Dispatcher.W_held_*,
BSPStepUpTests.{D4,C3}) remain failing — none introduced by this slice.

Reframes L.2d direction based on ACE BuildingObj.cs:39-52 + named-retail
acclient_2013_pseudo_c.txt:701260: retail's find_building_collisions is

L.2e territory.
Slice 1 is now a read-only BSP-hit diagnostic that captures full

Three new bullets, all evidence-driven from /insights:
"Only stop and wait for the user when":
- Request is an investigation/audit/analysis/review/report-only — no edits
or diagnostic drops until the user approves a fix. Use the /investigate
skill (local at .claude/skills/investigate/SKILL.md, gitignored).
- A referenced commit/path/branch/doc doesn't exist where the user said
it would — ask one short question; don't go hunting across branches.
Prevents the N.5-handoff-style 30-min wrong-branch exploration.
"What NOT to do":
- Don't replace working retail-faithful logic with a modern redesign
without explicit approval. Cites the 267 min remote-entity rewrite +
sky-fog shader speculation both reverted in full. Retail-faithful
first; "cleaner" second.
The /investigate skill itself stays local (option 3 — not committed).

Ships Phase L.2a (Truth & Diagnostics) for Movement & Collision Conformance,
plus the L.2d sub-direction call backed by reproducible evidence.
Three code commits:
- ebef820 — L.2a slice 1: [resolve] + [cell-transit] probes with DebugPanel mirror.
- e0c08bc — L.2a slice 2: extend [resolve] line with hit object guid + env flag.
- a068292 — L.2a slice 3: populate previously-stub CollisionInfo entity
attribution at the per-object call site in Transition.FindObjCollisions.
Plus a docs commit (eb401e8) shipping the cold-start handoff, next-session
prompt, L.2 plan-of-record shipped-slice notes, and CLAUDE.md status updates.
Three findings backed by reproducible Holtburg doorway evidence:
1. L.2e cell-id format gap: player CellId tracked as bare low byte
(0x00000029), no landblock prefix.
2. L.2c wall-slide working: clean clamping with correct normal, no ok=False.
3. L.2d sub-direction confirmed: 126/140 wall hits attributed to
obj=0xA9B47900 (landblock-baked building static); no door-range
entity ids appear. Fix is CBuildingObj + per-cell walkability port,
NOT door-state-toggle.
Build green; 1032/1040 unit tests pass. The 8 failing tests are
pre-existing on the branch base (verified by stash + rerun); none from
L.2a slice work.
Next session: L.2d slice 1 brainstorm + design spec
(docs/research/2026-05-12-l2d-next-session-prompt.md).

Documents the L.2a-slice-1/2/3 ship for the next session and updates
the project's source-of-truth docs to reflect current state.
New files:
- docs/research/2026-05-12-l2a-shipped-l2d-handoff.md — full cold-start
handoff: what shipped, three findings (L.2e cell-id format gap, L.2c
wall-slide working, L.2d sub-direction = CBuildingObj port), branch
state, diagnostic surface inventory, files changed, open concerns,
cold-start checklist, reproduction recipe.
- docs/research/2026-05-12-l2d-next-session-prompt.md — terse copy-paste
prompt for the next Claude Code session.
Modified:
- docs/plans/2026-04-29-movement-collision-conformance.md — added "Current
sub-direction" note under L.2d capturing the evidence-driven call:
building-mesh fidelity issue, not door-state-toggle.
- CLAUDE.md — updated "Currently between phases" → "Currently in Phase
L.2"; added L.2a shipped paragraph; added ACDREAM_PROBE_RESOLVE /
ACDREAM_PROBE_CELL to Diagnostic env vars; prepended L.2d brainstorm
to next-phase candidates list.
No code changes in this commit.

fields existed but were never written anywhere in the codebase — slice

no obj= attribution.
This commit fills the gap at the only place we have the attribution
data: the per-object iteration in Transition.FindObjCollisions, where
obj.EntityId is in scope right after each per-object BSPQuery /
CylinderCollision call. Two cases trigger an Add():
- result != TransitionState.OK (object hard-blocked transition)
- normal flipped invalid→valid during the call (BSPQuery captured
a slide normal without halting — covers wall-slide cases).
Beyond the diagnostic, this also fixes a quiet structural gap — any
future physics behavior that wants "who did I just collide with"
(PvP exemption sanity check, NPC bump rules, etc.) was previously
flying blind on stub fields. Now the data flows.
Build green. Will re-test the doorway with the same trace to get
the wall's entity id.

Extends the existing [resolve] probe line to surface
ci.LastCollidedObjectGuid (hit object) + ci.CollidedWithEnvironment
(terrain hit flag) + ci.CollideObjectGuids.Count (when >1) so the
operator can tell WHICH entity the wall is, not just the wall normal.
Tonight's L.2a slice 1 trace caught a clean wall-slide at the
Holtburg-area doorway (n=(0,1,0), 122 hit=yes lines), but had no way
to attribute the hit to a specific entity — the L.2d sub-direction
call (door collision shape vs building wall mesh) needs the entity id
to pick the right fix. This extension provides it on the next run.
Format change for [resolve] hit field:
Before: hit=yes n=(0.00,1.00,0.00)
After: hit=yes n=(0.00,1.00,0.00) obj=0xCC0CXXXX
hit=yes n=(0.00,1.00,0.00) env
hit=yes n=(0.00,1.00,0.00) obj=0xCC0CXXXX env nObj=3
Pure additive within the existing PhysicsDiagnostics.ProbeResolveEnabled
gate. No new env var, no new file. Build green.

New static `AcDream.Core.Physics.PhysicsDiagnostics` holds two
runtime-toggleable flags initialized from env vars:
- ACDREAM_PROBE_RESOLVE=1 — emit one [resolve] line per
PhysicsEngine.ResolveWithTransition call: input/target/output
position+cell, ok-vs-partial, grounded-in, contact-plane status,
wall normal if hit, walkable-polygon valid, moving entity id.
- ACDREAM_PROBE_CELL=1 — emit one [cell-transit] line per
PlayerMovementController.CellId change: old → new cell, current
world position, reason tag (resolver / teleport).
Both also exposed as runtime-toggleable checkboxes in the DebugPanel
"Diagnostics" section. Unlike the existing four Dump-* checkboxes
(which only mirror sticky-at-startup env vars), the two new ones
forward directly to PhysicsDiagnostics — toggling on/off takes
effect on the next physics resolve, no relaunch.
Why now: L.2's plan-of-record (docs/plans/2026-04-29-movement-collision-
conformance.md) explicitly says "Land L.2a diagnostics first. Do not
make another physics change blind." This slice closes the most-load-
bearing gap in L.2a — a general-purpose probe on the resolver outcome
and a cell-transit log — so that later L.2b/c/d/e physics changes can
be evidence-driven instead of guessed. Foundation for the indoor /
dungeon walking trajectory (G.3 unblock).
Pure additive: when both flags are off (default), the probes collapse
to a single static-bool read per resolve, zero log cost. PlayerMovement
Controller's two CellId-mutation sites are now routed through a
private UpdateCellId(reason) helper for diag chokepoint.
Build green, 1032/1040 unit tests pass. The 8 failing tests are
pre-existing on the branch base (verified by stash-and-rerun);
none touch resolver or cell-transit code; all fail identically with
this slice stashed. Investigation deferred to a follow-up.

Closes#56. Two coupled slices in one phase:
Slice A — ParticleHookSink honors CreateParticleHook.PartIndex. Adds
new SetupPartTransforms.Compute(setup) helper (walks PlacementFrames
[Resting] → [Default] → first-available, mirrors SetupMesh.Flatten's
priority); ParticleHookSink gains a per-entity part-transforms side-table;
SpawnFromHook now applies partTransforms[PartIndex] to the hook offset
before world-space rotation. Multi-emitter scripts distribute across
mesh parts instead of collapsing to entity root.
Slice B — EntityScriptActivator handles dat-hydrated entities. The
ServerGuid==0 early-return guard is relaxed: activator keys by
ServerGuid when non-zero, else entity.Id (collision-free in 0x40xxxxxx
range). Resolver delegate returns ScriptActivationInfo(ScriptId,
PartTransforms) so one dat lookup yields both pieces. GpuWorldState
fires the activator from 4 new dat-hydration sites (AddLandblock +
AddEntitiesToExistingLandblock for OnCreate, RemoveLandblock +
RemoveEntitiesFromLandblock for OnRemove). EnvCell statics + exterior
stabs (inn fireplaces, cottage chimneys, building decorations) now fire
their Setup.DefaultScript automatically.
Reality discovery during design (spec §3): EnvCell.StaticObjects are
already hydrated as WorldEntity instances by GameWindow.BuildInterior
EntitiesForStreaming with stable entity.Id — handoff §4 Q1/Q2 (synthetic
ID scheme, separate walker class) mooted.
Visual verification 2026-05-12: Holtburg Town network portal (entity
0x7A9B405B, script 0x3300126D) swirl no longer ground-buried, emitters
distributed across the arch; Holtburg Inn fireplace flames; cottage
chimney smoke; spell cast on +Acdream — all match retail.
18 new + 4 updated tests, all Vfx/Meshing/Activator/Streaming green.
8 pre-existing Physics/Input failures unchanged.

Roadmap:
- Status header now reads "Between phases" with C.1.5b in the recent-wins
bullet list.
- New SHIPPED row in the table (C.1.5b) summarising both slices, the
reality discovery about EnvCell statics, and the 4 visual-verified sites.
- The "IN FLIGHT — C.1.5b" sub-bullet under Phase C flipped to SHIPPED.
ISSUES.md:
- #56 removed from Active.
- #56 added to Recently closed with full commit chain (1e3c33b spec+plan,
f3bc15e SetupPartTransforms helper, 11521f4 ParticleHookSink part-transform,
5ca5827 activator refactor, 8735c39 GpuWorldState fire-sites), resolution
notes, and the visual-verification record.
CLAUDE.md:
- "Currently in flight" pointer replaced by a "Currently between phases"
marker + a C.1.5b shipped paragraph that's parallel to the existing
C.1.5a entry.
- "After C.1.5b" → "Next phase candidates".
Visual verification 2026-05-12: portal swirl matches retail extent + lateral
spread (no ground-burial); Holtburg Inn fireplace flames; cottage chimney
smoke; spell-cast particles on +Acdream — all match retail.

Four new foreach blocks in GpuWorldState wire EntityScriptActivator
into the dat-hydration spawn/despawn paths:
- AddLandblock: fires OnCreate for each entity with ServerGuid==0
(live entities filtered out — they got OnCreate at AppendLiveEntity
and would double-fire on pending-bucket merges).
- AddEntitiesToExistingLandblock: fires OnCreate for each entity in
the promoted batch (all dat-hydrated by construction).
- RemoveLandblock: fires OnRemove(entity.Id) for each ServerGuid==0
entity before the loaded record is dropped.
- RemoveEntitiesFromLandblock: fires OnRemove for the demote-tier
entities about to be cleared (Near→Far demotion).
5 new integration tests cover the four fire-sites + the no-double-fire
invariant on pending-bucket merges. Pattern matches existing
GpuWorldStateTests (stub LandBlock heightmap + WorldEntity factory).
Closes#56 end-to-end. Slice A (per-part transforms in Tasks 1-3) +
Slice B (dat-hydrated entity DefaultScript firing, this task) both
ready for visual verification at Holtburg portal + Inn fireplace +
cottage chimney + spell cast.
Note: 8 pre-existing failures in Physics/Input/MotionInterpreter test
families are unrelated to this work (verified by re-running with this
task's changes stashed).

Resolver returns ScriptActivationInfo(ScriptId, PartTransforms) — one
dat lookup per spawn yields both pieces of info. The C.1.5a ServerGuid==0
guard is relaxed: activator now keys by ServerGuid when nonzero, else
entity.Id, so dat-hydrated entities (EnvCell statics, exterior stabs)
flow through the same code path as server-spawned ones. PartTransforms
pushed into ParticleHookSink before scheduling Play, closing the
activator side of #56.
GameWindow resolver lambda upgraded: now constructs ScriptActivationInfo
from setup.DefaultScript.DataId + SetupPartTransforms.Compute(setup),
swallowing dat-lookup throws the same way C.1.5a did.
Tests: 4 existing tests updated for new ScriptActivationInfo signature;
3 new tests cover entity.Id keying for dat-hydrated entities, end-to-end
part-transform pipeline (resolver → sink → particle world position), and
OnRemove with an arbitrary caller-picked key. 77 Vfx+Meshing+Activator
tests green.
GpuWorldState fire-site wiring (Task 4) lands next.

Adds per-entity part-transform side-table mirroring _rotationByEntity.
SpawnFromHook now transforms the hook offset through partTransforms[partIndex]
before rotating to world space. Backwards-compatible: entities without
registered part transforms fall through to identity (pre-C.1.5b behavior),
so the existing C.1.5a rotation-seed test stays green.
Adds SetEntityPartTransforms public method. Cleared on StopAllForEntity
alongside the rotation entry.
2 new xUnit tests:
- SpawnFromHook_AppliesPartTransform_WhenRegistered — part 1 lifted +Z=1,
hook offset (1,0,0), PartIndex=1 → world (1,0,1).
- SpawnFromHook_FallsBackToIdentity_WhenPartIndexOutOfBounds — PartIndex=99
on a 2-part array → offset applied without crash, pre-C.1.5b behavior.
Closes the renderer side of #56. EntityScriptActivator wiring (Task 3)
lands next.

Computes Matrix4x4 per Setup part by walking PlacementFrames[Resting] →
[Default] → first-available, matching SetupMesh.Flatten's priority.
Foundation for #56 fix: ParticleHookSink will use these to apply each
CreateParticleHook's PartIndex-relative offset to the right mesh part.
4 xUnit tests cover Resting-over-Default preference, Default fallback,
empty-PlacementFrames returns empty, DefaultScale application.

Two-slice phase:
- Slice A: ParticleHookSink applies CreateParticleHook.PartIndex via
SetupPartTransforms.Compute(setup.PlacementFrames). Closes#56.
- Slice B: drop EntityScriptActivator's ServerGuid==0 guard so
dat-hydrated EnvCell statics + exterior stabs fire DefaultScript.
Key reality discovery folded into the spec §3: EnvCell.StaticObjects
are already WorldEntities (via GameWindow.BuildInteriorEntitiesForStreaming),
so no synthetic-ID scheme + no new walker class needed — the handoff's
§4 Q1/Q2 options are mooted by entity.Id being collision-free.
Doc-drift fixes from C.1.5a folded into §8.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Self-contained handoff doc for the C.1.5b session. §1 is a copy-paste
startup prompt for a fresh Claude Code session; §2+ is detailed
context (commits shipped in C.1.5a, decision space for the #56 fix
including precompute-per-spawn vs render-thread-side-table options,
EnvCell synthetic-id scheme, walker-class placement options, file
pointers, verification plan).
Slice will resolve issue #56 first (per-part transform handling for
static entities) before adding the EnvCell static-object DefaultScript
walker, per the C.1.5a final reviewer's recommendation that resolving
#56 unblocks slice 2's visual delight gate (the multi-emitter
collapse symptom affects portals, chimneys, and fireplaces alike).

Slice 1 of Phase C.1.5: fire Setup.DefaultScript through the already-
shipped PhysicsScriptRunner when a server-spawned WorldEntity enters
the world. Portals and any other static object with a DefaultScript
now emit their retail-faithful persistent particle effects at spawn
time, mirroring retail's play_script_internal dispatch on object load.
One new ~85-line orchestrator class EntityScriptActivator wires
alongside EntitySpawnAdapter in GpuWorldState's spawn lifecycle
(AppendLiveEntity → OnCreate; RemoveEntityByServerGuid → OnRemove).
Activator construction in GameWindow uses a defensive resolver lambda
over _dats.Get<Setup>(...) and also seeds _particleSink.SetEntityRotation
so hook offsets transform from entity-local to world space correctly.
Four xUnit tests with mutation-check verification. End-to-end: 8 commits,
every per-task commit reviewed for spec compliance + code quality;
final cross-task review by Opus approved.
Visual verification at the Holtburg Town network portal: 10-hook portal
script fires with correct color, persistence, orientation, and
multi-emitter dispatch.
Known limitation surfaced and filed as issue #56: ParticleHookSink
ignores CreateParticleHook.PartIndex, so multi-emitter scripts collapse
to one root position instead of distributing across the entity's mesh
parts. Visually produces a compressed, partly-ground-buried swirl on
multi-part dat objects. Mechanism is correct; per-part transform
handling is the next vfx-pipeline concern and blocks slice 2 (EnvCell
chimneys / fireplaces).

Issue: docs/ISSUES.md #56
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Visual verification at the Holtburg Town network portal passed for the
slice's mechanism: 10-hook portal script fires end-to-end with correct
color, persistence, orientation, and multi-emitter dispatch. After the
334f0c6 rotation-seed fix, the swirl is oriented correctly along the
portal's facing instead of world-NS.
Known limitation surfaced during verification and filed as issue #56:
ParticleHookSink ignores CreateParticleHook.PartIndex, so all 10 of the
portal's emitters collapse to the entity root position + identity-rotated
offset, producing a compressed and partly-ground-buried swirl instead of
the multi-tier shape retail renders. Mechanism is correct; per-part
transform handling is the next vfx-pipeline concern (will affect every
multi-emitter PES — slice 2 chimneys/fireplaces in particular).
Documentation changes:
- docs/ISSUES.md: new #56 entry with the captured entity guids
(0x7A9B405B / 0x7A9B4080), script ids (0x3300126D / 0x3300067A),
symptom data, root-cause hypothesis, file pointers, and acceptance
criterion. Notes the blocks-slice-2 relationship explicitly.
- docs/superpowers/specs/2026-05-12-phase-c1.5a-portals-design.md §9:
new limitation #1 documenting the verified PartIndex collapse symptom.
- docs/plans/2026-04-11-roadmap.md: new "C.1.5a" row in the shipped
table referencing the spec, plan, and #56 caveat.

Visual verification at the Holtburg Town network portal revealed the swirl
was oriented along world axes (NS) instead of the portal's actual facing
(EW), and partially buried in the ground because the hook's local-frame
Offset.Origin was being applied in world axes too.
Root cause: EntityScriptActivator.OnCreate fired _scriptRunner.Play but
never called _particleSink.SetEntityRotation. When the runner's
CreateParticleHook fires, the sink reads per-entity rotation from
_rotationByEntity (defaults to Quaternion.Identity for unknown entities)
and uses it to transform the hook's Offset.Origin from entity-local to
world space. Without the seed call, the rotation lookup falls through to
Identity and the offset goes off along world XYZ.
Fix is a single SetEntityRotation call before the Play call. Added a 4th
unit test that constructs an entity with a 90 deg yaw and asserts the spawned
particle's world position reflects the rotated offset.

Code-review follow-up to 65d833d:
ResolveDefaultScript was closing over its own var capturedDatsForActivator
= _dats, but the sibling SequencerFactory in the same block already
declared var capturedDats = _dats. The two locals pointed at the same
reference and served the same purpose; the alias added no value and
muddied the closure pattern.
Reuse capturedDats. No behavior change.

Wires the activator into the production lifecycle:
- Construct alongside _wbEntitySpawnAdapter using _scriptRunner +
_particleSink (both built earlier in OnLoad).
- Production resolver lambda hits _dats.Get<Setup>(...) wrapped in
try/catch returning 0 on miss/throw — matches ParticleRenderer's
defensive read pattern.
- Pass into GpuWorldState's new optional ctor parameter.
Closes the wiring half of C.1.5a. Visual verification at the Holtburg
Town network portal is the acceptance gate.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
GpuWorldState grows a fourth optional ctor parameter for the activator,
paralleling how EntitySpawnAdapter is plumbed. AppendLiveEntity calls
OnCreate after the existing _wbEntitySpawnAdapter?.OnCreate;
RemoveEntityByServerGuid calls OnRemove after the existing OnRemove.
Symmetric, same order, null-safe.
GameWindow still passes the old 3-arg ctor — activator construction +
wire-through lands in the next commit.

Code-review follow-up to 003c502:
1. Test 3 (OnRemove_StopsScriptsAndEmitters) now wires the runner into
the real ParticleHookSink instead of a RecordingSink, registers a
persistent EmitterDesc, lets the CreateParticleHook actually spawn an
emitter, then asserts the sink killed it after OnRemove. Previously
the test only verified runner-side state — sink.StopAllForEntity was
never observably exercised, so a regression dropping that call would
have passed silently.
2. Removed unused `using System.Numerics` from EntityScriptActivator.cs.
No production code changes. Tests 1 and 2 unchanged.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
New ~50-line orchestrator that fires Setup.DefaultScript through the
already-shipped PhysicsScriptRunner on entity spawn and stops scripts +
live emitters on despawn. Resolver delegate avoids DatCollection coupling
so the class is fully unit-testable with stubs.
Three xUnit tests cover the three branches: fire-with-script,
no-op-without-script, stop-on-remove. No wiring into the live spawn path
yet -- that lands in the next commit.
Spec: docs/superpowers/specs/2026-05-12-phase-c1.5a-portals-design.md

Plan: docs/superpowers/plans/2026-05-12-phase-c1.5a-portals.md. Four
tasks, TDD-style, each task is a single commit boundary:
1. EntityScriptActivator class + three xUnit tests
2. Wire into GpuWorldState (new optional ctor param + two ?. calls)
3. Construct in GameWindow with resolver lambda
4. Visual verification at Holtburg Town network portal + roadmap update
Spec amendments correct an inaccuracy in the 2026-05-12 commit
(06d7fbd): the activator's call sites live in GpuWorldState
(AppendLiveEntity / RemoveEntityByServerGuid), not directly in
GameWindow as the original spec described. Also fixes the test file
path: tests/AcDream.Core.Tests/... not AcDream.App.Tests/... per the
existing test-project convention. No design changes — same activator,
same trigger condition, same lifecycle ordering.

Slice 1 of Phase C.1.5: fire Setup.DefaultScript through the already-
shipped PhysicsScriptRunner on server-spawned WorldEntity create, so
portals (and any other entity with a DefaultScript) emit their retail-
faithful persistent particle effects at spawn time. Reuses the C.1
runner-sink-system-renderer chain end-to-end; one new ~50-line class
(EntityScriptActivator) plus a two-line wiring in GameWindow.
Slice 2 (C.1.5b) will cover EnvCell.StaticObjects + animation-hook
verification; spec landed separately after slice 1 verification passes.
Acceptance: visual confirmation at the Holtburg Town network portal,
side-by-side with retail.
